Qt 这个问题的解决方案我觉得是 QSignalMapper.但是我之前遇到过同样的问题，我发现使用部分"功能更简单.像这样使用它:

The Qt solution of this problem is QSignalMapper I think. But I had the same problem before, and I figured out using "partial" function is simplier. Use it like that:

from functools import partial

self.connect(self.Option1,SIGNAL("clicked()"), partial(self.myFunction, 1))
self.connect(self.Option2,SIGNAL("clicked()"), partial(self.myFunction, 2))
self.connect(self.Option3,SIGNAL("clicked()"), partial(self.myFunction, 3))
